Description

"Dispositif de production de boisson par infusion" "Device for producing beverage by infusion"
La présente invention concerne un dispositif de production de boisson par infusion d'un produit contenu dans une dosette.The present invention relates to a beverage production device by infusion of a product contained in a pod.
Elle trouvera particulièrement son application dans le domaine de la production de café à partir de mouture de café préemballée dans des dosettes.It will particularly find its application in the field of coffee production from ground coffee prepackaged in pods.
De telles dosettes existent par ailleurs déjà et sont généralement constituées sous forme d'un assemblage de deux feuilles de papier filtre réalisant un espace intermédiaire d'emballage de mouture de café.Such pods also already exist and are generally formed in the form of an assembly of two sheets of filter paper providing an intermediate space for packaging ground coffee.
Divers machines d'extraction de boissons chaudes à partir de mouture sont connues.Various machines for extracting hot drinks from milling are known.
Particulièrement, le document WO-A-00/38558 divulgue une chambre d'extraction pour machine automatique pour la préparation de boissons chaudes dans laquelle la chambre d'extraction est prévue pour recevoir des dosettes ou pastilles prédosées en café moulu.In particular, document WO-A-00/38558 discloses an extraction chamber for an automatic machine for the preparation of hot drinks in which the extraction chamber is designed to receive pods or pellets predosed in ground coffee.
La chambre est constituée de deux parties, chacune mobile dans un plan horizontale manière à pouvoir s'écarter ou se rapprocher l'une de l'autre.The chamber consists of two parts, each movable in a horizontal plane so as to be able to move away from or closer to one another.
Par ailleurs, selon ce document, les deux parties sont également mobiles de façon oscillante.Furthermore, according to this document, the two parts are also movable in an oscillating manner.
Une machine ainsi équipée donne globalement satisfaction mais nécessite l'entraînement des deux parties constitutives de la chambre. Il faut donc prévoir une motorisation suffisamment puissante et un système de transmission de puissance relativement complexe nécessitant la synchronisation des mouvement.A machine thus equipped gives overall satisfaction but requires the drive of the two constituent parts of the chamber. It is therefore necessary to provide a sufficiently powerful motorization and a relatively complex power transmission system requiring synchronization of the movements.
On connaît par ailleurs, du document FR-A-2.745.995 un appareil pour la fabrication de boissons dans lequel la chambre d'infusion est constituée par deux demi logements, l'un porté par une face du corps de l'appareil, l'autre fixé sur une face de la chaudière, ces deux faces étant en regard l'une de l'autre.We also know from document FR-A-2,745,995 an apparatus for the manufacture of beverages in which the brewing chamber is constituted by two half-housings, one carried by one face of the body of the apparatus, l another fixed on one face of the boiler, these two faces being opposite one another.
La chambre d'infusion est formée lorsque les deux demi logements se jouxtent.The brewing chamber is formed when the two half housings adjoin each other.
Cet assemblage de la chambre s'effectue par un mouvement de translation de l'un des logements.This assembly of the chamber is effected by a translational movement of one of the housings.
L'appareil ainsi présenté nécessite l'association de différents moyens de butée assurant la rétention de la dosette au moment de l'alimentation puis lors de son entrée dans la chambre d'infusion.The device thus presented requires the association of different stop means ensuring the retention of the pod at the time of feeding then during its entry into the brewing chamber.
Une mobilité des moyens de butées est également nécessaire pour assurer l'éjection des doses usagées.Mobility of the stop means is also necessary to ensure the ejection of the used doses.
L'art antérieur divulgué par cette antériorité impose la réalisation distincte de moyens de butée et d'éjection des dosettes.The prior art disclosed by this prior art requires the separate production of stop means and pod ejection.
La présente invention permet de remédier à ces inconvénients.The present invention overcomes these drawbacks.
Elle présente pour ce faire un dispositif de production de boisson améliorée.To do this, it has an improved beverage production device.
Un premier avantage de l'invention est de permettre la réalisation des phases d'ouverture et de fermeture de la chambre d'infusion ainsi que la réalisation des phases d'introduction et d'éjection de dosettes par l'intermédiaire d'un moins grand nombre de mouvement et, particulièrement, par le mouvement de rotation de translation combinée d'une seule des parties constitutives de la chambre.A first advantage of the invention is to allow the realization of the phases of opening and closing of the brewing chamber as well as the realization of the phases of introduction and ejection of pods via a lesser number of movements and, in particular, by the combined translational movement of rotation of only one of the constituent parts of the chamber.
Elle a vaincu le préjugé selon lequel la mise en butée de la dosette et la fermeture/ouverture de la chambre nécessitent la mobilité d'une pluralité de pièces : deux demi chambres ou butées additionnelles.It has overcome the prejudice according to which the abutment of the pod and the closing / opening of the chamber require the mobility of a plurality of parts: two additional half chambers or stops.
Un autre avantage de l'invention est de ne nécessiter dans un mode préféré de réalisation qu'un seul moyen d'entraînement pour un mouvement de rotation à un> mouvement de translation assurant ainsi à coup sûr et à moindre frais la synchronisation. Suivant une variante préférée, l'invention est telle qu'elle peut être utilisée et actionnée par un utilisateur par le biais d'un levier.Another advantage of the invention is that in a preferred embodiment only one drive means is required for a rotational movement with a> translational movement, thus ensuring synchronization without any cost. According to a preferred variant, the invention is such that it can be used and actuated by a user by means of a lever.
D'autres buts et avantages apparaîtront au cours de la description qui suit d'un mode de réalisation préféré de l'invention qui n'est cependant pas limitatif.Other objects and advantages will appear during the following description of a preferred embodiment of the invention which is not, however, limiting.
La présente invention concerne un dispositif de production de boisson par infusion d'un produit contenu dans une dosette, comportant une chambre d'infusion apte à recevoir une dosette et comprenant deux parties configurées pour être rapprochées ou éloignées pour fermer ou ouvrir la chambre d'infusion, caractérisé par le fait que l'une des parties a une mobilité en rotation apte à mettre en butée la dosette dans ladite partie, que la partie mobile en rotation a une mobilité en translation pour ouvrir ou fermer la chambre d'infusion, et qu'il comporte un moyen d'entraînement commun pour la mobilité en translation et la mobilité en translation de la partie mobile, ledit moyen d'entraînement comportant un arbre d'entraînement rotatif couplé à la partie mobile par au moins une biellette montée pivotante entre ledit arbre d'entraînement et ladite partie mobile.The present invention relates to a device for producing a beverage by infusion of a product contained in a pod, comprising an infusion chamber capable of receiving a pod and comprising two parts configured to be brought closer or apart to close or open the chamber. infusion, characterized in that one of the parts has a mobility in rotation capable of abutting the pod in said part, that the mobile part in rotation has a mobility in translation to open or close the infusion chamber, and that it comprises a common drive means for translational mobility and translational mobility of the movable part, said drive means comprising a rotary drive shaft coupled to the movable part by at least one link pivotally mounted between said drive shaft and said movable part.

- il comporte une chaudière située du côté de la partie fixe en rotation. Les dessins ci-joints sont donnés à titre d'exemples et ne sont pas limitatifs de l'invention. Ils représentent seulement un mode de réalisation de l'invention et permettront de la comprendre aisément. La figure 1 est une vue générale en perspective du dispositif de l'invention.- It includes a boiler located on the side of the fixed rotating part. The attached drawings are given by way of examples and are not limitative of the invention. They represent only one embodiment of the invention and will make it easy to understand it. Figure 1 is a general perspective view of the device of the invention.
La figure 2 en est une vue de dessus.Figure 2 is a top view.
Les figures 3 et 4 sont respectivement des vues de côté et en coupe longitudinale du dispositif de l'invention en position d'alimentation en dosettes.Figures 3 and 4 are respectively side views and in longitudinal section of the device of the invention in the pod supply position.
Les figures 5 et 6 sont respectivement des vues de côté et en coupe du dispositif de l'invention dans une position de réception de dosettes dans la chambre d'infusion.Figures 5 and 6 are respectively side and sectional views of the device of the invention in a position for receiving pods in the brewing chamber.
Les figures 7 et 8 sont respectivement des vues de côté et en coupe longitudinale du dispositif de l'invention en position d'extraction.Figures 7 and 8 are respectively side views and in longitudinal section of the device of the invention in the extraction position.
En se référant aux figures et particulièrement aux figures 1 et 2, le dispositif selon l'invention présente de façon conventionnelle une chaudière 9 apte à alimenter la chambre d'infusion 1 en eau chaude pour l'extraction de la matière contenue dans la dosette et particulièrement du café moulu.Referring to the figures and particularly to Figures 1 and 2, the device according to the invention conventionally has a boiler 9 capable of supplying the infusion chamber 1 with hot water for the extraction of the material contained in the pod and especially ground coffee.
Tel que présenté en figure 4, un circuit d'eau 10 est présent au travers du dispositif avec une partie 11 d'admission de l'eau chaude dans la chambre d'infusion 1 et une partie de sortie 12 débouchant sur une goulotte 13 déversant la boisson dans un entonnoir 14 jusqu'au récipient de l'utilisateur.As shown in FIG. 4, a water circuit 10 is present through the device with a part 11 for admitting hot water into the brewing chamber 1 and an outlet part 12 leading to a spout 13 discharging the drink in a funnel 14 to the container of the user.
Les dosettes utilisées pour le fonctionnement de la présente invention pourront être de type connues sur le marché actuellement.The pods used for the operation of the present invention may be of the type known on the market today.
De préférence mais de façon non limitative, on pourra utiliser les dosettes 2 comprenant une périphérie sensiblement plate et rigide assurant un maintien en forme de la dosette.Preferably but not limited to, it is possible to use the pods 2 comprising a substantially flat and rigid periphery ensuring that the pod is held in shape.
La chambre d'infusion 1 est constituée de deux parties 3, 4 aptes à être rapprochées pour fermer la chambre 1 tel que cela apparaît en figures 7 et 8 ou à être éloignées pour l'ouvrir comme cela ressort des figures 3 à 6.The infusion chamber 1 is made up of two parts 3, 4 able to be brought together to close the chamber 1 as shown in FIGS. 7 and 8 or to be spaced apart to open it as shown in FIGS. 3 to 6.
De façon préférentielle, et pour la suite de la description, c'est la partie 3 qui se déplace en translation pour se rapprocher ou s'éloigner de l'autre partie 4.Preferably, and for the following description, it is the part 3 which moves in translation in order to approach or move away from the other part 4.
Par ailleurs, la partie 3 est animée d'un mouvement de rotation de course limitée pour passer entre divers positions lors du fonctionnement.Furthermore, the part 3 is driven by a limited stroke rotation movement to pass between various positions during operation.
A titre préféré, on utilise un même moyen d'entraînement pour assurer la translation et la rotation de la partie mobile 3. On a repéré à titre d'exemple, en figure 4, la position de l'axe 8 de rotation de la partie mobile 3 et l'axe 7 de sa translation.Preferably, the same drive means are used to translate and rotate the movable part 3. As an example, in position 4, the position of the axis 8 of rotation of the movable part 3 and the axis 7 of its translation have been identified.
Pour la suite de la description et en référence aux dessins, on se place dans un exemple de machine à extraction horizontale (dans laquelle la dosette est positionnée sensiblement verticalement et reçoit l'eau chaude suivant un circuit sensiblement horizontal).For the remainder of the description and with reference to the drawings, we place ourselves in an example of a horizontal extraction machine (in which the pod is positioned substantially vertically and receives hot water in a substantially horizontal circuit).
Cependant, d'autres orientations sont possibles sans sortir du cadre de l'invention.However, other orientations are possible without departing from the scope of the invention.
Le moyen unique d'entraînement est constitué par un arbre d'entraînement 13 d'axe de rotation horizontal et apte à engendrer les mouvements de la partie mobile 3.The single drive means is constituted by a drive shaft 13 with a horizontal axis of rotation and able to generate the movements of the mobile part 3.
Pour ce faire, l'arbre 13 coopère avec au moins une biellette 14a, 14b mais préférentiellement deux biellettes.To do this, the shaft 13 cooperates with at least one link 14a, 14b but preferably two links.
Tel que cela est visible par exemple en figure 4, la biellette 14a, 14b est montée en liaison pivot 16, 17 d'une part sur l'arbre 13 et d'autre part, sur l'extrémité arrière de la partie mobile 3.As can be seen for example in FIG. 4, the link 14a, 14b is mounted in pivot connection 16, 17 on the one hand on the shaft 13 and on the other hand, on the rear end of the movable part 3.
Un organe translatif 21 est également prévu pour suivre solidairement le mouvement de translation de la partie mobile 3 et assurer l'articulation en pivot selon l'axe 8 de ladite partie mobile 3.A translating member 21 is also provided for integrally following the translational movement of the mobile part 3 and ensuring the pivot articulation along the axis 8 of said mobile part 3.
La translation de l'organe 21 est en outre guidée par des moyens de guidage qui pourront être constitués par deux guides latéraux 30a, 30b comme cela ressort de la figure 2.The translation of the member 21 is further guided by guide means which may consist of two lateral guides 30a, 30b as can be seen in FIG. 2.
Suivant une première possibilité, l'arbre 13 est entraîné en rotation par une motorisation.According to a first possibility, the shaft 13 is driven in rotation by a motorization.
Suivant une seconde possibilité, envisagée dans les figures, l'entraînement en rotation s'effectue par le biais d'une levier 15 pouvant être actionné par l'utilisateur.According to a second possibility, envisaged in the figures, the rotation drive is carried out by means of a lever 15 which can be actuated by the user.
Dans ce cadre, la partie mobile 3 est inclinée vers le bas pour réaliser une surface de butée 6 en sa portion supérieure pour coopérer avec la surface extérieure inférieure de la dosette 2.In this context, the movable part 3 is inclined downward to produce an abutment surface 6 in its upper portion to cooperate with the lower external surface of the pod 2.
La surface 6 constitue ainsi une butée en phase d'alimentation de la dosette 2. Pour optimiser l'étanchéisation de la chambre d'infusion 1 en position fermée, il peut être avantageux d'ajouter à la pression de fermeture opérée par l'utilisateur au moyen du levier 15, une pression additionnelle.The surface 6 thus constitutes a stop in the feeding phase of the pod 2. To optimize the sealing of the brewing chamber 1 in the closed position, it may be advantageous to add to the closing pressure operated by the user by means of the lever 15, an additional pressure.
Dans ce cadre, un moyen de serrage en fermeture des deux parties 3, 4 de la chambre d'infusion 1 peut être constitué en complément.In this context, a clamping means for closing the two parts 3, 4 of the brewing chamber 1 can be constituted in addition.
A titre d'exemple préféré, on utilisera des moyens de serrage sous forme de vérin hydraulique à membrane dont la membrane mobile est apte à engendrer un léger déplacement de la partie 4 de la chambre d'infusion.As a preferred example, clamping means will be used in the form of a hydraulic cylinder with a membrane, the movable membrane of which is capable of causing a slight displacement of part 4 of the brewing chamber.
Tout autre moyen de serrage est également envisageable.Any other clamping means is also possible.
De façon avantageuse, le dispositif comprend également des moyens de guidage de la dosette 2 lors de son déplacement durant les phases de fonctionnement.Advantageously, the device also comprises means for guiding the pod 2 during its movement during the operating phases.
Dans ce cadre, on pourra constituer des moyens de guidage sous forme d'une glissière 25 constituée par deux rainures 26 aptes à encadrer la périphérie de la dosette 2.In this context, it is possible to constitute guide means in the form of a slide 25 constituted by two grooves 26 able to frame the periphery of the pod 2.
La périphérie de ladite dosette 2 peut s'insérer dans chacune des rainures 26 ainsi constituées.The periphery of said pod 2 can be inserted into each of the grooves 26 thus formed.
Des moyens de guidage sont avantageusement montés translatifs pour suivre le mouvement de rapprochement ou d'éloignement des deux parties.Guide means are advantageously mounted translative to follow the movement of bringing together or moving away from the two parts.
En ce sens, ces moyens ont un déplacement couplé à celui de l'organe translatif 21 par l'intermédiaire de poussoirs 31 représentés notamment en figure 3.In this sense, these means have a displacement coupled to that of the translational member 21 by means of pushers 31 shown in particular in FIG. 3.
Le poussoir 31 comprend une partie en créneau 32 apte à constituer deux portions d'appui du poussoir 31 sur une surface correspondante des moyens de guidage.The pusher 31 comprises a slot portion 32 capable of constituting two bearing portions of the pusher 31 on a corresponding surface of the guide means.
De cette façon, le mouvement des moyens de guidage suit celui de l'organe translatif 21 au cours des phases de fonctionnement.In this way, the movement of the guide means follows that of the translational member 21 during the operating phases.
Par ailleurs, le vide constitué entre les deux surfaces d'appui formées par le créneau 32 assure un retard dans le déplacement des moyens de guidage apte à assurer d'abord une avance de la partie mobile 3 seule puis une avance couplée du moyen de guidage et de la partie mobile 3 vers la partie fixe 4. Le système à poussoir ainsi constitué peut être réalisé de façon guidée autour de deux guides latéraux 30a, 30b assurant le guidage en translation des éléments mobiles et la cohésion des pièces constitutives du dispositif.Furthermore, the vacuum formed between the two bearing surfaces formed by the slot 32 ensures a delay in the movement of the guide means capable of first ensuring an advance of the movable part 3 alone and then a coupled advance of the guide means and from the mobile part 3 to the fixed part 4. The pusher system thus formed can be produced in a guided manner around two lateral guides 30a, 30b ensuring the guiding in translation of the mobile elements and the cohesion of the constituent parts of the device.
Les phases de fonctionnement du présent dispositif sont plus particulièrement illustrées aux figures 3 à 8.The operating phases of this device are more particularly illustrated in FIGS. 3 to 8.
Les figures 3 et 4 montrent une première position de fonctionnement du dispositif dans laquelle la dosette 2 est en position de butée sur la paroi supérieure de la partie mobile 3.FIGS. 3 and 4 show a first operating position of the device in which the pod 2 is in the abutment position on the upper wall of the movable part 3.
Le levier 15 est lui dans une position angulaire prédéterminée ici verticale.The lever 15 is itself in a predetermined angular position here vertical.
Un actionnement du levier 15 dans le sens trigonométrique permet de parvenir à la position illustrée aux figures 5 et 6 dans lesquelles la dosette 2 est reçue dans la partie mobile 3.An actuation of the lever 15 in the counterclockwise direction makes it possible to reach the position illustrated in FIGS. 5 and 6 in which the pod 2 is received in the movable part 3.
Entre ces deux phases de mouvement, l'arbre d'entraînement 13 a provoqué un appui de la biellette 14a sur la partie arrière de la partie mobile 3 et a particulièrement provoqué une rotation de la partie mobile dans le sens horaire.Between these two phases of movement, the drive shaft 13 caused the rod 14a to press on the rear part of the movable part 3 and particularly caused the movable part to rotate clockwise.
En poursuivant la rotation du levier 15, l'arbre 13 engendre une poussée supplémentaire sur la partie mobile 3 par l'intermédiaire des biellettes 14a, 14b, cette poussée supplémentaire tendant à la translation de la partie mobile 3 et à sa fermeture pour constituer la chambre d'extraction 1.By continuing the rotation of the lever 15, the shaft 13 generates an additional thrust on the mobile part 3 by means of the connecting rods 14a, 14b, this additional thrust tending to the translation of the mobile part 3 and to its closing to constitute the extraction chamber 1.
On peut prévoir des surfaces de butée notamment sur l'organe translatif 21 pour limiter la mobilité angulaire de la partie mobile 3.One can provide abutment surfaces in particular on the translational member 21 to limit the angular mobility of the mobile part 3.
Ainsi, dans la position représentée aux figures 7 et 8, la partie mobile 3 clôt la chambre d'extraction 1.Thus, in the position shown in FIGS. 7 and 8, the mobile part 3 closes the extraction chamber 1.
Dès que la chambre d'infusion est fermée, l'eau chaude est injectée dans la chambre d'infusion.As soon as the brewing chamber is closed, hot water is injected into the brewing chamber.
La boisson est récupérée dans la goulotte 13.The drink is collected in the chute 13.
Dès que la lixiviation est opérée, un mouvement inverse de l'arbre 13 induit un recul de la partie mobile 3 et son pivot dans le sens trigonométrique.As soon as the leaching is carried out, a reverse movement of the shaft 13 induces a retraction of the mobile part 3 and its pivot in the trigonometric direction.
La partie mobile s'esquivant, la dosette 2 peut être libérée et chuter par gravité vers une zone de récupération. La position ainsi pivotée de la partie mobile 3 vers le bas assure la formation à nouveau de la surface 6 de butée d'alimentation en partie supérieure de la partie mobile 3.The moving part dodging, the pod 2 can be released and fall by gravity to a recovery zone. The downwardly pivoted position of the movable part 3 ensures the formation of the feed stop surface 6 in the upper part of the movable part 3 again.
Les figures 3, 5 et 7 illustrent en vue de côté la réalisation du mouvement de translation des moyens de guidage lorsque ceux-ci sont présents.Figures 3, 5 and 7 illustrate in side view the realization of the translational movement of the guide means when these are present.
A ce sujet, on visualise le poussoir 31 apte à provoquer l'avancée des moyens de guidage 25 au fur et à mesure de l'avancée de la partie mobile 3.In this regard, the pusher 31 can be seen which is capable of causing the advance of the guide means 25 as the movable part 3 advances.
Le créneau 32 présent sur le poussoir 31 assure cependant un retard dans la translation des moyens de guidage 25.The slot 32 present on the pusher 31 nevertheless ensures a delay in the translation of the guide means 25.
La fin de l'évacuation de la dosette 2 s'opère dès que la partie mobile 3 est reculée et alors que les moyens de guidage 25 sont encore en position.The end of the evacuation of the pod 2 takes place as soon as the movable part 3 is moved back and while the guide means 25 are still in position.
Une fois que la dosette est évacuée, les moyens de guidage 25 subissent à leur tour une translation.Once the pod is removed, the guide means 25 in turn undergo translation.
Le retard opéré dans la translation des moyens de guidage 25 assure le bon décollement de la dosette 2 avant le retour en position initiale complet du dispositif. The delay in the translation of the guide means 25 ensures proper detachment of the pod 2 before returning to the complete initial position of the device.
